IF it started out from rest, then V = a t = (7.8 x 30) = 234 meters per second
in the direction of the acceleration, at the end of 30 seconds.

An object's velocity changes from 30 meters per second to 23 meters per second in 3 seconds What is is its acceleration?
-2.33 metres per second squared
What are the units of acceleration?
Acceleration is a change in velocity per unit of time. Velocity is distance (d) per unit of time (t). That makes acceleration distance per unit of time squared, or something like this:We have distance/time2, or d/t2Distance is commonly measured in meters, and time in seconds. This makes acceleration appear in meters per second per second, or meters per second squared, or m/sec2.m/s2meters per second squared
If a trucks brakes are applied for 2 seconds giving it acceleration of -3.1 ms2 what will the trucks new speed be in ms?
No starting velocity was given, so I can't give a correct answer, but I can answer part of the question. Given an acceleration and a time through which an object accelerates, you can determine the change in velocity. Acceleration is just the change of velocity over a period of time. Since we have an acceleration of -3.1 meters per second squared, acting for two seconds, we have a change in velocity of -6.2 meters per second. Take the original velocity and subtract 6.2 meters per second to get the answer.
What is acceleration time graph?
The change in the velocity divided by time in meters per second squared.
What is the centripetal acceleration of an object being swung on a string with a radius of 3 meters at a velocity of 4 meters per second?
Use the formula for centripetal acceleration: velocity squared / radius.
What is the velocity if travel 5.7 meters per second squared for 4 seconds?
Velocity can be measured in metres per second, not metres per second squared. Acceleration is measured in metres per second squared but knowing only the acceleration does not help in finding the velocity.
When acceleration occurs?
Acceleration occurs when velocity changes over time. The formula for it is as follows: a = (Vf - Vi) / t a: acceleration (meters/seconds2) Vf: Final velocity (meters/seconds) Vi: Initial Velocity (meters/seconds) t: Time (seconds)
An object's velocity changes from 30 meters per second to 23 meters per second in 3 seconds What is is its acceleration?
-2.33 metres per second squared
If an aircraft on its take-off run has a steady acceleration of 3 meters per second squared what velocity does the aircraft gain in 4 seconds?
The velocity gained by the aircraft in 4 seconds can be calculated using the formula: velocity = acceleration × time. Given acceleration of 3 m/s^2 and time of 4 seconds, the velocity gained by the aircraft would be 12 meters per second.
What are the significant similarities and differences between velocity and acceleration?
Velocity and acceleration are both vector quantities that describe motion. Velocity is the rate of change of an object's position over time, while acceleration is the rate of change of an object's velocity over time. In simpler terms, velocity tells us how fast an object is moving and in what direction, while acceleration tells us how quickly the velocity is changing, either by speeding up, slowing down, or changing direction.
What are the units of acceleration?
Acceleration is a change in velocity per unit of time. Velocity is distance (d) per unit of time (t). That makes acceleration distance per unit of time squared, or something like this:We have distance/time2, or d/t2Distance is commonly measured in meters, and time in seconds. This makes acceleration appear in meters per second per second, or meters per second squared, or m/sec2.m/s2meters per second squared
Why do we a use the units meters per second squared when we talk about acceleration?
For every second of acceleration the velocity is increased by that acceleration.
What forces are difined as?
Acceleration is the change in velocity (m/s) divided by time (s), which is the same as meters divided by time in seconds squared (m/s2).
What does the slope of an acceleration-position graph indicate?
Meters/seconds squared
